摘要
以江苏省常州市金坛区水资源概况为背景,应用WinSRFR模型(用于地表水灌溉)与SWAP模型(用于地下水灌溉)的组合模型对农田水利灌溉效率进行优化.结果表明,SWAP模型模拟结果显示项目区所需的灌溉深度约为75 mm,而WinSRFR模型模拟结果显示灌溉深度可以大幅缩减,并使灌溉效率从47%提高到92%;使用改进的WinSRFR模型优化灌溉方案,可实现有效节水和农作物产量增加.
Abstract
Based on the overview of water resources in Jintan District of Changzhou City,Jiangsu Province,the combined model of WinSRFR model(for surface water irrigation)and SWAP model(for groundwater irrigation)was used to optimize the efficiency of agricultural water conservancy irrigation.The results show that the required irrigation depth of the project area is about 75 mm simulated by the SWAP model,whereas the irrigation depth simulated by the WinSRFR model can be significantly reduced.And the latter increases the irrigation efficiency from 47%to 92%.Optimization of irrigation schemes using the improved WinSRFR model can achieve effective water conservation and increase crop yield.
